METALLIC BUILDING CONSTRUCTION.

Specication of Letters 'Patent Patented May 6, 149.13.

To all whom z't may concern:

Be it known that I, ASHEL W. CRorsLY, a citizen of the United States, residing at f Cook and State of Illinois, have invented certain new and useful Improvements in Metallic Building Constructions, of which the following is a specification.

This invention relates to metallic building constructions' such as grain-bins, garages and similar structures and aims to produce ,a building of this character which can be knockdown condition and can be shipped in readily and easily put together and taken apart by unskilled labor. ,l

I am aware that sectional metallic building constructions have been` made prior to my invention but these constructions have been assembled by bolt-ing the sections together, ,this construction necessitating, of course, accurately and precisely located so that they will correspond and aline with the companion holes on the `section to be joined thereto.

My present invention aims to eliminate as far as possible the bolting of the various sections together and in order to accomplish this result I employ clips or other similar devices for securing the adjacent parts together, thus obviatng the dithculties in assembling the construction which are presented when the bolt holes in the various parts are -not accurately and precisely located.

The principal aim, therefore, of this invention is to produce a sheet-metal con-` struction which shall be strong, rigid and durable, which shall be Wind and vermin proof and which shall comprise comparatively few parts of simple construction capable of being manufactured at small expense and adapted to be readily and quickly assembled with a minimum amount of labor.

The invention will be best understood by reference to the following descriptionwhen taken in connection with the accompanying drawings illustrating one preferred embodiment thereof. v

On the drawings-Figure 1 -is a front elevation of an embodimentof the invention. Fig. 2 is a fragmentary section on a large scale through the roof and side-walls. Fig. 3 is a fragmentary sect-ion on 'anenlarged scale through the side-walls and floor.

F 1g. 6 is a sectional elevation on the line 6 6 of Fig. 5, showing the roof plates and cap in position. Fig. 7 is a fragmentary sectional view showing one method of joining the adjacent roof plates. Fig. 8 is a sectional view showing the manner of joining the sheet-metal sections forming the side-walls. Fig. 9 is an enlarged fragmentary sectional view showing the manner of attaching the upper angle iron to the sidewall. Fig. 10 is a sectional elevation showing a central bracket for supporting the center hoop. Fig. 11 is a sectional view disclosing the manner of interlocking the roof plates. Fig. 12 is a plan viewof the floor Fig. 13 is a sectional view on the line 13--13 of Fig. \12. Fig. 14 is a fragmentary elevation of a central portion ofthe side-wall; and Fig. 15 is a sectional view onthe line 15-15 of Fig.`14.

The ,side-walls of the construction comprise a plurality of sheet-metal sections 12 vertically in'g from top to bottom of the side-walls. The verticaledges of these sections are folded back upon themselves as indicated at 13 in Fig. 8 so that the. edges of adjacent sections may be brought into interlocking engagement. Bolts 14 are preferably inserted through the interlocked edges to fasten the sections together and prevent the. structurefrom collapsing. It will be noted from Fig. 8. that the edges of the secti'ons are turned back farther atone side than at the other so that the bolts 14 pass only through three thicknesses ofthe metal and this construction has been found sufficiently strong for all purposes although it will be obvious that both edges might be turned back the same distance and perforated so that the fastening bolts 14 would extend throughV four thicknesses of metal, if preferred. Each of the side sections is interlocked with its adjacent sections in this manner except at one ppint on the circumference of the building ,lwhere Ithe lasttwo sections to be assembled\are joined in the'manner shown inFigs. 14 and 15. One edge of each of these sections has an` angle iron 12 riveted thereto, the adjacent flanges of said angle iron projecting inwardly as shown in Fig.

disposed and preferably extend- 15. These flanges are provided with holes through which the boltsll are passed and when the nuts on these bolts are drawn up the angle irons and the sections 12 are drawn together to form a close joint at this point.-

The lower ends of the sections are bent-inwardly as indicated at 15 in Fig. 3, and m the angle formed by these inturned ends -with the vertical portions of the sections ed to slip over and embrace the vertical sections, have their flange of the angle iron thereby preventing spreading of the sections away from the iron. To assist these clips in maintaining the sections in position and to prevent spreading of the construction yat the bottom, a hoop 19 is placed around the construction to encircle and embrace t-he lower ends of the section and clips 20, secured by rivets 21 or other preferred fastening means tothe inturned ends 15l of the outer ends 22 upturned and spaced fro-m the side sections to receive and support said hoop in position. A similar hoop 23 encircles the construction intermediate the ends of the side sections and this hoop is supported by clips or bracket-s 24 (Figs. 1 and 10) secured by bolts or rivets 25 to the side sections as shown. The ends of the -hoop 23 are provided with perforations 23, as shown in Figs. 14 and 15, and bolts 24 are passed through these perforations to bolt the ends of the hoop to the vertical angle irons l2. are drawn together by thebolts 11 the ends of the hoop are drawn past each other and the hoopis tightened around the structure.l

An angle iron 26 surrounds and embraces the side sections near their upper ends, as shown in Fig. 9, and this angle iron is supported in position by clasps 27 which surround the iron and are'secured to th side sections by boltsor rivets 28. It will be obvious that t-hese clasps may be attached to the side sections very readily and thatl no bolt holes through the side sections need be alined in order to assemble the construction. The side-walls of the construction are thus surrounded, embraced and strengthened at their bottom, center and top by the hoops 19, 23 and the angle iron 26, respectively, and all of these encircling bands may be placed in position without regard to their angular relation to the walls and without alining any formed of angle irons.

When the angle ironsv through the angle iron and bolt holes in the encircling bands with companion holes in the side sections. The advantages'both in the manufacture and in the erection of this construction over the constructions in which the encircling bands are bolted in position, will be readily 'appreciated.

The framework of the roof comprises a plurality of main. rafters 29 preferably The vertical flange 30 of each rafter is removed adjacent the outer end thereof, as shown in Fig. 2, and the horizontal flange 31 is bent downwardly to rest upon the upper face of the horizontal flange of the angle iron 26. The vertical flange thus terminates inside the vertical walls of the construction while the outer end of the horizontal flange is secured by bolts 32 or other fastening means to the angle iron 26. The vert-ical flanges 30 are also cut away adjacent the inner ends of the rafters and the horizontal flanges 31 are bent to assume a horizontal position, 'as shown in Fig. 6, and these bent portions are provided with perforations which are alined to receive a .fasteningfg' bolt 33 which securely fastens the inner ends of the rafters together at the apex of the roof. Transverse members 34 (Fig. 4) are fastened at each end to the main rafters intermediate their ends and auxiliary rafters 35 are fastened at their upper ends to these transverse members and are bolted at their lower or outer ends to the angle member 26 main rafters 29 are fastened to this angle member. This construction affords a strong, rigid roof structure adapted to support the roof proper. The roof itself consists of a plurality of metal roof plates 36 made narrower at their inner ends than at their outer so that they will completely cover a circular building such as is shown. The side edges of most of the plates are folded back upon themselves. as indicated at 37 in Fig. 11, so that the adjacent plates may be interlocked in a manner similar to the interlocking of the side-wall sections previously described, but in order that the roof plates may be more rigidly secured together and prevented from becoming displaced every fourth or fifth plate has one edge folded vertically as indicated at 38 in Fig. `7 and the adjacent 'edge of the next plate is folded in the form indicated by 39 to fit over the fold 38, so that the sections may be securely fastened together by bolts or rivets 40. While I have shown every fourth plate as provided with a vertical flange adapted to form a joint such as shown in Fig. 7 it will be obvious that all of the plates may be fastened together in this manner, if preferred, and, furthermore, in some constructions it may not be necessary to employ this type of joint but all of the plates may be interlocked in the manner disclosed in Fig. 11. The inin the same manner that thev turned ends 41 and the top of the seams 39.

The bolt 33 which fastens the apex of the roof together passes through the cap 42 and through the perforations in the inner ends 31 of the rafters and when the nut is threaded tightly onto the bolt, the cap, roof plates and the rafters are all firmly clamped together thus producing a strong and rigid construction at the apex of the roof.

It will be noted that the clasps 27 which support the angle iron 26 in position space this angle iron from the side sections of the wall a distance equal to the thickness of the sheet from which the clasps are made. These spaces formed between the adjacent clasps 27 are adapted to receive fastening devices 43 (Fig. 2) which are secured by rivets 44 to the roof plates 36. These fastening devices consist of strips of metal which are inserted between the angle iron 26 and the side sections, the lower ends of each device .being then bent upwardly as indicated at 44 to embrace the vertical flange of the angle iron 26. The roof plates are thus rigidly secured to the angle iron 26 and the side-Walls, the roof-frame and the roof plates are origidly and securely bound together. When the building construction is to be used as a grain-bin, an opening through which the grain may be introduced directly from the threshing-machine into the bin is provided in the roof and this opening may be normally closed by a suitable cover 45. A manhole 46 is also provided and a plurality of openings 47 through which the grain may be removed are formed in the side sections, these openings being normally closed by any preferred type of cover or closure.

The floor which is designated generally as 48 consists of a plurality of metal floor plates 49 made narrower at their inner ends than at their outer, as shown in Fig. I2; the outer ends of the plates being riveted to the angle iron 16, as shown in Fig. 3, and theA inner end being riveted to a central plate 50. The floor plates are arranged in sections the plates in each section having their. side edges turned back upon themselves to interlockingly engage, as indicated at 51 in Fig. 13. One of the outer plates.

vof each section has its edge bent downwardly and then outwardly as indicated at 52, while the opposite plate of the section has its outer edge bent rearwardly, then downwardly and outwardly as indicated at 53 to form a groove or pocket into which the projecting lip 52 of the adjacent section fits. This joint between the sections presents a smooth upper surface and produces a close joint between the sections, thereby ormmg a strong -and rigid floor construc- `It is believed that the construction and many advantages of my present invention will bevunderstood from the foregoing without further description and it will be obv1ous that various changes. in the size, shape, arrangement and proportion of the various parts may be resorted to without departing from the spirit or sacrificing any o f the material advantages of the invent1on.

I claim:
